The invention discloses a mixed breeding method of
rana nigromaculata and rice, and relates to the technical field of breeding. The method comprises the following steps: three parallel water ditches are dug in a
paddy field with a length of 10 m and a width of 9 m along a length direction, distance between two adjacent water ditches is 3 m, a width of each water
ditch is 1 m, a depth of each waterditch is 1.4-1.6 m, a length of each water
ditch is 10 m, one rice area is arranged between two adjacent water ditches, the periphery of the
paddy field is fenced by adopting a fence net, rice is planted in the rice areas, after the rice grow for 20 days, the young
rana nigromaculata is stocked in the water ditches, a
mixed solution of water and a tobacco stem extract liquid is sprayed to the rice every 8-10 days, and earthworms and fly maggots are thrown in the
paddy field a next day after the tobacco stem extract liquid is sprayed every time. According to the mixed breeding method of the
rana nigromaculata and the rice disclosed by the invention, in a mixed breeding manner of the
rana nigromaculata and the rice, rice planting does not need pesticides to kill insects, the produced rice is green and
pollution-free, and pests bred in the rice planting process provide a sufficient food source for breeding of the
rana nigromaculata, so that the production costs are reduced.
